throughout.
* pinfo.cc (set_myself): Pass INVALID_HANDLE_POINTER if h is NULL.

to open it only when necessary.

* spawn.cc (spawn_guts): Ditto.
* miscfuncs.cc (winprio_to_nice): New function.

* include/cygwin/version.h: Bump API minor version.
* include/sys/resource.h: Add PRIO_XXX defines and prototypes for
getpriority and setpriority.
loop since trying multiple times to call CreateFileMapping doesn't make much
sense. Try to structure the loop a little better so that exiting with a break
does the right thing.
(pinfo::release): Release shared memory area if it exists and close handle if
it exists.
has exited before getting an error code.
(pinfo::exit): "cd" to innocuous location before exiting to make sure that
process does not keep the current working directory busy while it is in the
process of really exiting.
(CoUninitialize): Remove.
(CoCreateInstance): Remove.
(CoTaskMemFree): Add.

header structure.

an ITIMIDLIST in the file.
* pinfo.cc (pinfo::exit): Use renamed function.
(proc_waiter): Ditto. Make a copy of input argument to avoid problems when
procs array is shuffled. Flag when copy is made so that remove_proc knows when
it is safe to reshuffle.
* sigproc.cc (proc_terminate): Don't flag process_state as PID_EXITED.
(remove_proc): Wait for waiter to finish copying pinfo element before moving it
(an actual wait should be an extremely rare event).
* strace.cc (main): Recognize new option for displaying hex value of strace
type.
(handle_output_debug_string): Prepend output with hex value of strace message
if -H is specified.
* include/sys/cygwin.h: Remove PID_ZOMBIE.
* pinfo.h: Rename EXITCODE_* defines.
(pinfo::set_exit_state): Remove parameter.
* pinfo.cc (set_exit_state): Remove parameter. Reverse sense of test so that
exitcode is checked for having been set rather than not having been set. Set
flag when exitcode has been established. Don't set PID_STATE here.
(pinfo::init): Remove exitcode initialization.
(pinfo::exit): Reflect change in EXITCODE_* naming. Set flag when exitcode has
been established. Reflect change in arguments to set_process_state.
(proc_waiter): Reflect change in arguments to set_process_state. Set
process_state here and only here.
* fhandler_process.cc (fhandler_process::fill_filebuf): Reflect removal of
PID_ZOMBIE define.
(format_process_stat): Ditto.
(format_process_status): Ditto.
* sigproc.cc (pid_exists): Ditto.
(stopped_or_terminated): Ditto. Make sure that only low-order 16 bits of
exitcode are used.
* spawn.cc (spawn_guts): Reflect change in EXITCODE_* naming.
SETACL if no acls are available.
* fhandler.cc (fhandler_base::facl): Implement to return sensible
values on GETACL and GETACLCNT. Pretend successful SETACL.
* fhandler_virtual.cc (fhandler_virtual::facl): Ditto.
* fhandler_disk_file.cc (fhandler_disk_file::touch_ctime): New method
to set file's ctime.
(fhandler_disk_file::fchmod): Try opening file for writing first.
Set file's ctime on success.
(fhandler_disk_file::fchown): Ditto.
(fhandler_disk_file::facl): Ditto.
* fhandler.h (select_record::thread_errno): Save any encountered errno here.
(select_record::set_select_errno): New function.
(select_record::saw_error): New function.
(select_record::select_record): Initialize thread_errno to zero.
* select.cc (set_handle_or_return_if_not_open): Set thread_errno on failure.
(select_stuff::wait): Record errno for later resurrection in calling thread.
(peek_serial): Ditto.
* mkpasswd.c (print_win_error): Transform into macro.
(_print_win_error): Upgrade former print_win_error by
printing the line.
(current_user): Call _print_win_error.
(enum_users): Print name in case of lookup failure.
(enum_local_groups): Ditto.
(pinfo::exit): Move here from _pinfo::exit.
* sigproc.cc (child_info::sync): Use new function to set exitcode and
process_state.
* pinfo.cc (_pinfo::exit): Ditto.
(proc_waiter): Ditto.
(_pinfo::set_exit_state): Define new function.
(_pinfo::dup_proc_pipe): Close handle when there is no parent process around to
care about the exit value.
* dcrt0.cc (dll_crt0_0): Move subproc_ready synchronization later to make sure
that myself is still mapped in parent.
(do_exit): Reflect movement to pinfo::exit.
(__api_fatal): Ditto.
* exceptions.cc (signal_exit): Ditto.
* errno.cc (errmap): Map PROC_NOT_FOUND.
* init.cc (dll_entry): Release myself before exiting.
* sigproc.cc (proc_can_be_signalled): Set errno appropriately.
(sig_send): Ditto. Also remove ill-advised test for !myself->sendsig since
this is an indication of a process which is still initializating -- it is not
an error.
(child_info::sync): Don't set exitcode here. Assume that will happen in
proc_waiter, if necessary.
* spawn.cc (spawn_guts): Delay "wait_for_myself" logic until later. Don't wait
at all if the process has already exited. Reflect movement to pinfo::exit.
